Police said Johnson is 34, although jail records list her as 31. She was being held Wednesday in the Gregg County Jail on $500 bond for allegedly giving false information to police. Attorney information was not listed for her.

Stiles said she did not know why the woman posed as a teen.

The principal at New Life Christian School in Longview said Johnson enrolled in October with a guardian and filled out paperwork indicating she was 15.

"She acted like a 15, 16-year-old. She was an attentive student, respectful, did her homework," Stuart Newlin told The Associated Press.

He said the school charges $150 a month, but there's no penalty if students don't pay. He said she'd been paying about $24 a month tuition at the school with about 30 students.

He said everyone involved with the school was convinced she was a teen.

"The why? Nobody seems to know why," Newlin said.

Stiles also said she did not know what Johnson's motivation was.

Tamica Lincoln told KLTV television station in Tyler that she invited Johnson into her home in March after Johnson told her she needed a place to stay.

"I sympathized with her, and invited her into my home. I took her in as a child, did her hair, got her clothes and shoes," Lincoln said.

She called police after suspecting Johnson was using a fake identity.

"I just don't know why she did it," Lincoln told the television station.

Johnson Deceived Founder of Dallas Non-Profit Organization

A Dallas woman said she was nearly fooled by Johnson as well.

Osarieme Obaseki said Johnson contacted her through her non-profit organization that helps victimized children.

She claimed Johnson said her parents were dead and that she was a rape victim.

Obaseki said they developed a mother-daughter like relationship. Johnson even came to Dallas to visit Obaseki on Mother's Day. During the trip, the two snapped pictures she shared with NBC 5.

Obaseki claimed she knew something wasn't right and that her family insisted Johnson wasn't a teenager based on how she acted. However, Obaseki said Johnson looked, acted and sounded like a 15-year-old girl who had lived a rough life.

Obaseki claims encouraged Johnson's roommate in Longview to do some digging and that's when Johnson's alleged lies began to unravel.

Obaseki also said she's made contact with women in other states who claim Johnson deceived them as well.

NBC 5's Bianca Castro contributed to this report.
